VDA-204 Dual 1x4 Video Distribution Amplifier


The VDA-204 consists of two independent 1 input, 4 output video distribution amplifiers.

Gain and equalization are adjustable for each amplifier, and the controls are accessible from the front of the unit.

The video inputs are looping. All input and output connections are made via BNC type connectors.
